Исследование пьезоэлектрических материалов с низкой температурой спекания
Акимов, А. И.; Савчук, Г. К.; Жуковец, Д. А. (БНТУ, 2009)It is established, that the piezoceramic materials on the basis of 0,41PNN- 0,23PZ-0,36PT solid solutions can be received on liquid-phase sintering procedure M temperatures 960-1100°C. It is received, that introduction of micro additives leads to change of parameters of a crystal lattice and growth of temperature of phase transition. The perspectivity of use of 0,41 PNN-0,23PZ-0,36PT ...2021-09-22 -
Условия получения и диэлектрические свойства СВЧ материалов для малогабаритных антенн
Акимов, А. И.; Савчук, Г. К. (БНТУ, 2009)Dielectric properties of ceramic materials of the Zn2Ti04 - ТiО2 binary system are studied. The influence of the Sn+3, Sb+3, Bi+3 doping ions on dielectric proper ties of ceramic samples of the Zn2Ti04 - ТiО2 system is investigated. It is found that the SHF materials with e<30 and tg6 of about 0.0001 can be prepared by modi fying the Zn2Ti04 - Ti02 ceramics. It is shown that the ...2021-09-22 -
Условия получения и пьезоэлектрические свойства материалов системы 0,2PB(NB2/3Zn1/3)03-0,8(PBZt 0,5Ti0,5)03, легированной галлием и ванадием
Акимов, А. И.; Савчук, Г. К; Летко, А. К.; Степанова, Л. И. (БНТУ, 2009)Piezoelectric properties of ceramic materials of the 0,2Pb(Nb2/3Zni з)О3- 0,8(РЬ2го.5ТІо 5)О3 system are studied. The influence of the Ga +3, V+5 doping ions nn piezoelectric properties of ceramic samples of the PNZ-PZT system is investigated. It is shown that pretreatment of powder mixture allows to decrease the calcinations temperature on 150°C and to receive the ceramics with ...2021-09-22
